Nah I don't think it should of been longer. Maybe at the max one or two more episodes but nothing past that. This anime doesn't have that feel to be a long anime series. 12 was good enough to cram each characters' path and story together. The art does remind me of Grenadier though.

They didn't even really address their plot, I was thinking when they said to set out to change the world, they would have massive battles and fight the reigning bandit army or get some magic relic to restore peace. But, most of the episodes were focused around comedy and ecchi, and only one big battle scene...YES I would definitely want more than 12 episodes.

They should have a season where there is a war between Gender Binded and their opposite (our world) selves due to a feud between one of the kingdoms and their opposite selves, OR they found their gender binded universe, and wanted to take power there or something... either way, it would have some plot like that.
